The ADG5436F is an analog multiplexer, containing two resistance of the ADG5436F, combined with the on-resistance independently selectable single-pole, double-throw (SPDT) flatness over a significant portion of the signal range, makes it switches. An EN input is used to disable all the switches. For use an ideal solution for data acquisition and gain switching in multiplexer applications, both switches exhibit break-before- applications where excellent linearity and low distortion are make switching action. critical. Each channel conducts equal y wel in both directions when on, Note that, throughout this data sheet, the dual function pin names and each switch has an input signal range that extends to the are referenced only by the relevant function where applicable. See supplies. The digital inputs are compatible with 3 V logic inputs the Pin Configurations and Function Descriptions section for over the full operating supply range. full pin names and function descriptions.
